Claims.

My invention relates to lubricating means for comb bars and bobbin shuttles for lace loom-s and has particular reference to means whereby lubricating oil is deposited along the bases of the bobbin shuttles. By capillary attraction the oil spreads onto the base of the bobbin shuttles and is transmitted from these shuttles to both sets of comb bars commonly used in lace looms thereby providing lubrication for these shuttles necessary for their satisfactory operation and for the purpose of reducing the wear to these operating parts.

Another and further object of my invention is the provision of lubricating means, including an oil reservoir for the reception of oil, having a wick therein which is so'mounted that a substantial part of the Wick is held in engagement with the bobbin shuttle so that oil will beconveyed from the reservoir onto the bobbin shuttle'in the somewhat small quantity desired and necessary for the lubrication of these parts.

Heretofore in the lubrication of these particular parts of a lace loom, manufacturers have depended upon graphite, preferably in powdered form, which is distributed lightly over the comb bars or directly onto the bases of the bobbin shuttles. When the operation of the loom is started,

usually in the morning, the operator prior to starting the loom or in the initial stages of its operation applies the powdered graphite to these operating parts with one application usually being sufficient to keep the parts lubricated throughout the day. A great deal of difficulty has been experienced in the use of powdered graphite because it is very light and is easily carried from one part of the loom to another and to the material being loomed, as well as in the air around the looms, where it lodges ofttimes in the Workmens clothes, on the floor of the weaving room wherevit becomes attached to the soles of the shoes'of the operators and is carried about the premises to such an extent that constant cleaning operations are necessary, both with respect to the premises themselves and the looms on which the graphite is used and the premises where the looms are located.

Another and further object of my invention is tached thereto;

111., a. corporation of Illinois 7 Y Application March 13, 1947, Serial ,No. 734,453" 1 These and other objects of m invention will be more fully and better understood by reference to the accompanying sheet of drawings in which:

Figure 1 is a sectional elevational view through a lace loom showingjf' y lubricating means at- Figure 2 is 'a side elevational view showing the lubricating means and thefsides of the shuttles commonly employed in a l-see loom;

Figure 3 is a sectionalview through the lubricating device itself; I i

7 Referring now specifically to the drawings and in which like reference characters refer to like parts throughout, frame members H] and. II, which form-a part ofthe loom, are provided upon which the usual comb bars l-Z'and l3- are mountedwithin which-theshuttles such as I4, M are positioned, the base-"Hi f'which is shown in engagement with the comb bar I2and has the usual hooks l6, It at each end thereof'by means of which the bobbin shuttles. are actuated through the warps I], l1 and between the bars l2 andl3 in the usual fashion of the operation of these parts, which is well understood in this art.

A bobbin [8 of circular :form is'mounted on the shuttle M having a thread'lq'extending upward therefrom to'a nose piece 20,-also of the usual form, all of these parts beingcommon to looms of this type and well known'in the art.

The lubricating device comprises a 2 bar 2| having a baseifiange 22,- a .web23 and an upper flange 24' having an edgeflangeZ la therealong which is disposed atan angle to the upper flange '24 with the .outer face of-the' edge flange 24a extending generally parallelto the base I5 of the shuttle Hi. An oil reservoir 25 preferably of tubular form, and of any desirable or convenient length is provided having plugs 26, 21 in each of its ends and having 'a continuous slot 28 in the upper side thereof with spaced oil holes 29, 29 therein also being positioned toward the upper side of the reservoir526, but in slightly offset relation with respect to the continuous slot 28. The reservoir 25 isbrazed. or otherwise attached to the base flange 22 along its lower side and to the Web 23 along its side adjacent the web 23, so that the reservoir'2'5 is firmly secured to the 2 bar 2|. The base 22 and web 23 are thereforeheld together as aunit-but the :upper flange 24 is flexible 'due to the :thin character of the metal of which the 2 bar is made so the oil wick hereinafter described is kept in close contact with the bobbin shuttle; An elongated wick 3flzisiprovided which at one of its sides extendsgthrough .thezislots28 and into the oil reservoir 26, and extends upward therefrom across the face of the upper flange 24 and against the inner face of the edge flange 25 and thence at an angle substantially parallel to the base 15 of the shuttle I4 and has a substantial portion in contact with the outer edge of the base I5. 2

A bar 3| is provided having an angularly disposed inner edge 32 extending at substantially the same angle as the inner face of the edge flange 24a and against which the wick is positioned, this bar 3| being held in place by screws 33, 33 extending into the upper flange portion 24 of the Z bar 21 thereby holding the wick 30 flrmly in position on the 2 bar 21 and also holding the free upper edge portion in proper angular position for engagement with the base [5 of the bobbin shuttle I4. The reservoir 25 is slightly less in length than the Z bar 2|, so the base flange 22 of the 2 bar extends beyond the ends of the oil reservoir 25, which is engaged by clamps 34, 34 with screws 35 therein by means of which the Z bars including the reservoir 26 are clamped to the upper face of the frame members It], as is shown, particularly in Figure 1, where a plurality of oiling devices is shown mounted on the front of the loom. One of the clamps 34 overlaps the adjacent ends of the lower flanges 22 of the abuting Z bars, so that the oil devices are firmly held in position on the upper face of the frame member ID. If it is desired to remove or replace these devices for any purpose whatsoever for the replacement of the wicks or the like, the members can be easily removed by loosening the screws 35 and removing the clamps, thereby loosening the 2 bars 3! so they can be easily removed and replaced. if desired, or the 2 bars may be moved toward or away from the bases of the shuttles l4, M in order that the wick be held in engagement therewith.

As will be noted, particularly with reference to Figure 2, the upper portions of the wick are somewhat wider than. their lower portions with the edges 36, 36 of the wicks being carved slightly to accommodate them in the reservoir 25 and provides suificient width to the wicks so that each of the bobbin shuttles isincontact with the upper free edge of the wick 30 when the device is in position on the loom.

In operation the oil device is attached to the loom as heretofore described and at proper intervals the operator fills the reservoir 26 with oil, preferably of a light, clear semi-penetrating variety and by capillary attraction the wick becomes saturated with oil and is brought into contact with the base of the bobbin shuttles with each movement of the bobbin shuttles into contact with the wick 30 because of the elasticity of the upper flange 24 of the 2 member so the oil passes to the bases of the bobbin shuttles and thence to the comb bars, so that but the shuttle bars and combs are kept sufliciently and adequately lubricated without an excessive amount of oil being applied to the parts which would be absorbed by the goods being woven or which would drip onto other parts of the machine. In this manner these parts are adequately lubricated, insuring their proper operation and lengthening their life without the disadvantages attendant on the use of graphite as hereinabove described.

Also a small amount of oil will travel across the base of the bobbin shuttles to the edge of the bobbins so the bobbins will also be lubricated without oil coming in contact with either woven 4 material or the various threads from which it is woven.

While I have described more or less precisely the details of construction, I do not Wish to be understood as limiting myself thereto, as I contemplate changes in form-and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
